Hi everyone,
I'm working on a project using the S32K358 microcontroller and interfacing it with an AT25QF641B serial flash memory via the QuadSPI interface.
While exploring the available software support, I came across the MEM\_43ExFls driver in the S32K3 RTD package. It looks like this driver is intended for external flash memory, possibly over QSPI, but I couldn’t find clear documentation or a reference project that demonstrates how to configure and use it with a third-party flash like the AT25QF641B.
Has anyone used the MEM\_43ExFls driver to communicate with non-default or custom QSPI flash devices?
Here are a few specific questions I have:
* Are there any reference examples or demo projects using MEM\_43ExFls with external flash on S32K358?
* What steps are needed to configure the driver for AT25QF641B (e.g., device ID, command set, memory map)?
* Any recommendations or caveats when integrating third-party flash chips with this driver?
Any help, pointers, or shared experience would be greatly appreciated!
Best regards,
M.J.David
